My use case scenario is different from many. Up and down steep winding mountain roads ehich I tend to drive as aggressively as safety, traffic, and road conditions allow. I’ve been “one pedal driving” my MS for nearly 12 years. But on the mountains i have need for my brakes on the regular. So repeated use of brakes is still in my “driving vocabulary” even with max regen. To me the brakes will absolutely matter.

I also find no shortage of individuals that fail to check before lane changes or to signal beforehand and in those scenarios regen isn’t gonna’ cut it.

Cheers
Are you saying you think they might overheat on a mountain pass descent? My experience is you will be nowhere near their heat threshold, even if driving irresponsibly fast and braking into corners.

Sure, step it up to racetrack speeds for an extended session and you will feel fade and have to back off. But that's not how Cybertrucks are driven on the road. Any car with stock brakes will overheat if you bring the brakes to their thermal limit by alternating full acceleration and full braking for a long enough period of time.

So to clarify, my question about people’s thoughts was not really an invitation to challenge why i would care about brakes and i’m not here to bash the CT… far from it.

My question is about brake venting with wheels like this. Let’s say its the middle of summer and you are hauling a trailer down the mountains from tahoe in heavy traffic and have to use the brakes over and over in summer heat as a result. Would wheels like this worry you?

That’s a more specififc way to ask my question. I really don’t need a lesson on Tesla one pedal driving. I’d be willing to bet I’ve been doing it since before most people on this forum had ever even heard of Tesla. So if we could stick to the point I would prefer that rather than questioning the validity of my question, and my question is about this wheel design relative to venting brakes.

I don’t really see a need to get huffy about it. Some people haul weight downhill. Some people drive faster than others, and not on straight flat roads. Some people drive where their fellow drivers aren’t so aware of the traffic around them. Brakes matter. These wheels seem like they could cause an issue with brakes to me but otherwise I quite like them. If people with some automotive design knowhow or greater knowledge of materials physics than I have actually have strong opions about this, I would like to hear them.

Thanks in advance.

The non-vented wheels probably can't help but reduce the thermal capacity of the brakes. Wheels are a significant exit path for brake heat, but I assume the solid disc wheels probably don't radiate more than a vented wheel. The question is, how extreme the brake usage would need to be to overcome the brakes thermal capacity.

A heavy trailer shouldn't tax the brakes of the tow vehicle because heavy trailers need their own brakes and shouldn't be increasing the braking required by the tow vehicle at all. The only exception to this rule would be if you tuned (backed off) the brake controller to create more regen opportunity for the tow vehicle. And that's for experts only because it could end badly if you don't know what you're doing. The "proper" way to tune the brake controller is for the trailer to add no significant pushing force to the tow vehicle. Thus there should be no significant additional brake heat generated due to the trailer.

Personally, I would worry more about the brakes on your typical trailer than the ones on the Cybertruck (because they don't have regen helping them out).

Folks are getting all worked up about the wheels being bullet proof. ? I highly highly doubt the intent was to design the wheel being bullet proof as a feature. It is more of a effect of design and materials that makes it bullet proof as side effect. This is no different than the CT body panels. Its purely a sarcastic marketing gimmick. Could have just as easily called them "Tactical" wheels. LOL

Unless tires are going to be bulletproof, I don’t understand the need for these wheels but maybe it’s just me.

It’s good to see a different approach to designing CT wheels though.
I want airless tires
